after the iMac has been turned off and back on? The message I receive is more or less "Time Machine failed because the HDD is read only".
Simple question I can't find the answer to. Or am I seriously meant to leave the iMac on 24/7?

As a matter of interest, how do you get it to work again?
This is not typical behaviour and may indicate a fault with the backup disk. The first step would be to run "repair permissions" on it. You may want to check this article: https://www.lifewire.com/fix-time-machine-errors-225...

Agree with Tiny - I'd suspect a faulty HDD. Run Disk Utilities over it as a first step.

Remove drive from USB Cable (its already been uncounted), then reconnect to usb cable then use Time Machine Preferences to allocate the drive.
I have run repair permissions and it finds nothing. Everything is fine if I leave the iMac on, it just seems after I have rebooted this problem occurs.

Did you run Disk First Aid in Disk Utilities?
|
|
|
Yes I have
However I have noted that the MAC HDD is APFS and the backup is MacOS Extended (Journalised) - could that be the problem?

Nope.
What did Disk Utility say about the Ext HDD?
|
|
|
that its perfect.
Mind you, I have realised what caused the problem (well it seems ok at the mo). The WD driver software was missing, I've downloaded it and had two successful shut downs without Time Machine throwing the failed error.

Urgh.
Failed again after reboot
Files can�t be copied onto the backup disk because it is read-only. You may need to repair or erase the disk using Disk Utility. If the disk can�t be repaired, select a different disk for backups.
Immediately, I used First Aid to check both the volume Time Machine and the actual drive. Both said no problems.
Going to leave the imac on and will see if backup fails again.

I'd be inclined to try a different backup drive. That would help to pinpoint whether the problem is with the drive or the computer.
External drives shouldn't require any drivers for normal operation.

Hmm. As Tiny says, WD drivers shouldn't be an issue. On Macs at least, you just format and go.
I'd be inclined to invest in a new Ext HDD - you can get 2tb rugged USB3 LaCie's for £65. Since the old drive is still readable, you would still have the archive if you need it (plus you can never have too many backups).

Thanks Both - looks like it might be a fault on the drive then? I had another failure when I was away this morning and the next one that just finished was ok. Didn't even touch the drive. Drive I am using at present is a WD My Passport, its being used as backup since last June and before then as a backup for my photos on a desktop.

I'd say it is certainly not reliable as a backup anymore. Time for a new drive.
It might be worth launching the mac in recovery mode (hold down cmd-R while booting) and running disk utilities over the start up drive, just to be safe. It take sages, though...
